COLLAPSIBLE XYLOPHONE-STAND.

To all 'whom it may concern.'

Be it known that I, CHARLES B. VANA- MAKER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Collapsible Xylophone-Stand, of which the following is a specification.

The object of my invention is to produce a collapsible stand especially adapted for supporting xylophones, or other similar musical instrument elements, in playing position, the structure being very light and collapsible into small compass, yet, when extended, pos? sessing ample rigidity to sustain the musical elements, though sutliciently flexible to stand firmly upon uneven surfaces.

The stand is especially useful to vaudeville performers who are compelled to carry y their instruments about from town to town and to set them up for use upon stages which are often rough, warped and uneven.

The accompanying drawings illustrate my invention. l

Figure 1 is a perspective view of the stand in expanded position ready for use; Fig. 2 a transverse section showing one expanded end in elevation; Fig. 3 ajview of the parts shown in Fig. 2, in collapsed posil tion; Fig. 4 a side elevation of the main frame in collapsed condition; Fig. 5 a perspective detail showing the detachable connection between one of the supporting arms and a platform bar; Fig. a longitudinal section of the parts shown in Fig. 5 when said parts are assembled; Fig. 7 a vertical sectional detail of one of the collar latches; Fig. 8 a side elevation, about full size, of the detachable connection between the braces between the end standards; Fig. 9 a section on line 9 9 of Fig. 8; Fie: 10 a perspective view of one of the platform bars folded; Fig. 11 a fragmentary plan showing the brace between two adjacent platform bars.

In the drawings, A and B indicate a pair of end standards or frames which are substantially identical as to construction, though varying slightly in proportion of parts@ Each of these standards comprises a central` post 10 which is preferably tubular so as to be light but strong. Secured to the upper end of post 10 is a collar or cap 11 to which is pivoted, at 12, an arm 13 having a brace 15 Specification of Letters Patent.

pivoted at 1G, to its outer end. Below cap 11, on post 10, is a collar 17 to which is pivoted, at 1S, an arm 19 said arm being supported by a brace 21, pivoted at 22. Arranged between cap 11 and collar 17 is a collar 23 provided with an ear 24; to which is pivoted the upper end of a brace 25.

The two braces 25 are brought together and pivotally connected to a pair of plates 26, 26 which are provided with a central perforation 27. The outer plate 26 is provided with a latch 28, the purpose of which will appear.

It will be readily understood that the collars 11, 17 and 23 might be formed in one piece if desired and the arrangement be such that arms 13 and 19 would be on the same level, but the arrangement shown is preferable because, as will appear later, supports at two different levels are provided, as is quite common in Xylophone supports.

Pivoted te the pivots 12 and 18 are the upper ends of a pair of legs 31, 31 each provided with a suitable foot 32 at its" lower end. Vertically slidable on post 10 is a collar 33 to which are pivoted braces 34 which extend in opposite directions and are pivotallya connected to the lower ends of legs 31.

In order to limit the downward movement of collar 33 on post 10 I provide a collar 35 at the lower end of said post, and this collar carries an ear 3G to which is pivoted the lower end ofa brace 37 similar to brace 25.

The two braces 37 have their upper ends pivotally connected to a pair of plates 38, 38, and extending through these plates and secured rigidly thereto is a pin 39 adapted to be projected through openings 27 of plates 26. The outer end of pin 39 is provided with a notch or groove 41 adapted to receive latch 28. The ends of braces 25 are extended beyond their pivots Ll2, and these extended ends lie between plates 26 so as to thus stiffen the pivotal connection. It is desirable that these braces come together as closely as possible and their ends are therefore beveled, at 43, so that they will abut when brought to the position shown in Figs. 1 and 8, and notches 14 are provided to permit the passage of pin 39. Similarly the upper ends of braces 37 are extended between plates 38 beyond their pivots 45, andthese extended ends are beveled, as indicated by dotted lines at' 46 in Fig. 4, and provided with notches to fit over pin 39 when the parts are expanded, as shown in Figs. 1 and 8.-

In order to prevent the legs 31 from being twisted with relation to post 10, I provide the sliding collar 33 with notches 47 (Fig.

which, when the collar is in its lowest position, will straddle a pin 48 projecting transversely from the lower end of post 10.

The lower ends of braces 15 and 21 are brought toward each other and pivotally connected to a sliding collar 51 mounted upon post 10 and movable downwardly from the position shown in Figs. 1 and 2 to the position shown in Figs. 8 and 4. This collar 51 is held in upper position by means of a spring latch 52 pivoted at 53 within post 10 and normally urged outwardly by a light spring 54. The latch 52 is provided with a shallow notch 55 adapted to receive the lower edge of collar 51 and at this point is provided with a nger projection 56 by which it may be pressed backwardly into the interior of post 10. The latch 52 is also provided with projection 57 which lies a distance above the bottom of the notch 55 equal to the vertical height of collar 51 plus a trifle more than the depth of the notch, the projection 57 thus preventing too great upward movement of collar 51. This arrangement facilitates t-he very rapid expansion of the collapsed structure, as it is impossible to carry collar 51 to a height greater than projection 57 thus bringing the arms 13 and 19 to horizontal positions.

Each arm 13 and 19 is preferably formed of a short piece 0f angle iron with one arm of the angle arranged to form a horizontal ledge, and this horizontal ledge is provided with one or more perforations 61. In order to form a support for the Xylophone elements I provide several platform bars C which are arranged in pairs to form two rigid platforms. Cf course a different horizontal support or platform for the Xylophone elements might be provided, but as most of these elements are iiexibly connected so that they may be rolled into small compass, I deem it desirable to so form the platform bars that they may be folded into a compass which is no greater in any dimension than the collapsed main frame, as illustrated in Figs. 3 and 4. It is for this reason that the separate bars C are provided. Each of these bars comprises a plate 62 the edges of which are turned up at 63 to form a channel, the upper edges be ing further bent inwardly to form converging lips 64. The space between portions 63 and below lips 64 may be conveniently filled with a bar of light wood 65 the upper surface of which will thus form a bottom or support for a strip of felt 66 which will be held in place by the lips G4. The felt 66 serves as a direct support for the Xylophone elements. Each bar C is preferably formed of two parts hinged together at 67 so that it may be folded to the condition shown in Fig. 10. At each end each bar C is )rovided with a hook 68 having a downturnet finger adapted to fit into one of the perforations 61 and, in order that each platform may be secured against accidental displacement, I provide the ends of the outer bar C of each pair with a spring bolt 69 adapted to project beneath the horizontal flange of the arm 13 or 19 and coperate with hook 68, as clearly shown in Fig. 6. The bolt 69 is normally urged outwardly by a light spring 71, and the bolt and its spring may be conveniently mounted in a folded-metal casing 72 to the upper side of which the hook (38 may be secured (as clearly shown in Fig. 6), the said casing 72 being slipped into the end of bar C and secured in place by rivets 73.

Hinged at 75, to either the outer or inner bar C, is a brace 76 having a notched end 77 which may be thrown behind the head 78 of a pin projecting from the adjacent face of the companion bar C, so that, when the parts are assembled as shown in Figs. 1 and 11, the two companion bars C are transversely braced7 one by the other.

Vith the bars in the position shown in Fig. 1 the structure may be quickly collapsed in the following manner. Braces 7 (i will be first swung backwardly so as to withdraw hook 77 from behind head 7S. Bolt (3S) will then be pushed back so as to permit hooks (SS to be withdrawn from holes (i1 so that the outer bars C may be lifted away and folded as shown in Fig. 10. The inner bar C may then be lifted off and folded. Collars 33 may then be drawn upwardly on posts 10 and collars 51 moved upward slightly so as to permit catches 52 to be pressed back into the posts whereupon they may be shoved downwardly so as to swing arms 13 and 1S) downwardly toward post 10. Thereupon catch 28 may be thrown upwardly to the position shown in dotted lines in Fig. 8 and pin 89 pushed (to the right Fig. 5)) out of plates 26 to separate the lower ends of braces 25 from the upper ends of braces 27, whereupon plates 2G may be moved downwardly and plates 28 may be moved upwardly so that the braces 25 and 37 will collapse and the two posts 10 be brought together, as shown in Fig. 4. The parts are thus very closely compacted and the bars C in their folded condition may then be packed upon the collapsed frame and bound together by straps or otherwise.

The method of expanding the structure will be readily apparent from what has been said.

The braces 25 and 37 and the platform bars C serve to very rigidly connect the two end standards against any improper displacement but, nevertheless, there is suilicient flexibility in these braces, and in the connections between the bars C and the supporting arms 13 and 19, that the four points of support provided for' the feet 43 need not be in exactly the same plane, as will be readily apparent. Any inequality of this kind will, of course, result in a slight wind in the relative positions of' the platform bars C but, as the Zylophone elements are themselves flexibly connected, this slight wind is of no consequence. On the other hand it is very important that the supporting structure be of such character that it will be firmly positioned upon uneven surfaces.
